Kubota Group enjoy various world records:

Prof. M. Kubota together with Dr. Bob Mueller (front middle in photo) were the major persons who started ultra low temperature physics in 1980 with the first achievement of Micro-kelvin physics study.

Kubota group at ISSP built the world fastest rotating cryostats to study fundamentals of superfluds and quantum vortices.

Fundamental study of Quantized vortices: vortex state, vortex dynamics.  etc.



Major Equipments


ULT rotating Cryostat

Currently superfluid 3He is studied under rotation up to +- the world fast rotation record 6.28 rad/sec.


High Speed Rotating Cryostat

Vortex physics of ideal 3D superfluid made from 4He monolayer films condensed on 3D connected surface is being studied. Currently modification for supersolid study is in progress.
